Medium to large patches running along slopes in a wide band
Steep, sheltered, rocky, middle to lower slopes, typically slightly concave (dish-shaped) and facing north, northwest, or east
Acidic soils (but containing moderate levels of plant nutrients); often thin due to steep slopes
Rocky outcrops or boulderfields; underlying bedrock geology is Weverton Formation (quartzite), Harpers Formation (metasilstone and sandstone), or Tomstown Formation (dolomite and limestone)
